Application filed March.

This invention relates to spacing can ri: s, and more particularly to spacing car- T12 s for punching machines andthe like,

and has for one oi its objects the provision oi a novel form oi adjustable stop mechanisnrior such carriages which will perm t the work-piece to. be moved through the Inachine shorterdistances than the stopmechan l IlO.V' gQI1QlHll in use, andtherei ore permit the closer spacing of work operations. i i i i 'l'eete' er pa g car iage r ranc machines and the like have generally been provided with a f xed rack on the carriage'table, and a plurality of stops removably mounted in the rack for adjustment to various positions within limits, and a stop plunger-carried by the carriage and adapted to cooperate with the stopsin said rack to limit the movement of said carriage, the plunger being mounted ,for vertical movement only. :With this stop mechanism, the number of stops used and their adjustment was limited.

Another object of this invention is to provide means for adjusting the stop plunger relative to the carriage, in addition to the adjustment of the stops in the racl: and, therefore, provides a greater and finer range of adjustment than possible with the stop mechanism heretofore in use.

A (further object is to provide a spacing carriage of the class described, having the novel design, construction, and combination of parts hereinafter described, and illus trated in the accompanying drawings.

In the drawings- Figure 1 is a plan view of a spacing carembodying my invention.

Figure 2 is a side elevationthereoi.

prises a body portion 3 having ELXiQS 4 on which are journaled wheels 5, adapted to travel on thesides of the table 2.

The table 2 has toothed racks (Sextending longitudinally along each side thereof, and theicarriage is provided with rack pinions 7 on a sliai t 8, which pinions mesh w h the racks 6 to propel the earriage'longitudinally of the" table, when the shait rotated. The shaft .8 isprovided with a suitablei l1and)vlieelil for manual rotation lIBQi. 3 A suitable -spacing rack 10 is mounted on the one sid'e of the table 2 and is provided with suitable spaced serrations or slots ll for the reception of stop members 12. The slots 11 are'so spacedthat the'stop members may be adjustedto various positions, such adjustments, however, are limited to the spacing ofthe slots 11.

"A stop plungerl is mounted for vertical movement in a suitable housing-15, which is sli dahly mounted between guides 16 'on'the carriage body 3. The plunger 14 is adapted to be moved vertically to clear the'stop menibe'rs 12 by a lever 17 fulcruinedat 18 on the housing and eonnec tedat 33 to the'upper end of the plunger. The rearward end of the'leveifll'f' projects beyond the plungerl l and aeoi'l tension spring19 has one end connected to the projecting rearward end of the grip the work-piece A, so that the work piece w lll'ie no-ved throughthe machine as the carriage is moved.

The plunger nouslng 1 5 is provided with a toothed rack 21,"and a rack' p nion 22 18 mounted on asha'ift 23, journaled' in suit-able bearings 24 oirtlie guides 161 "Thepinion is in mesh with the rack 21 and is-adaQted to cause noveinent of the housing 15 longiof the carriage pody :wh en the i on- 1S rotated; 4 P s i The sp i davith an operating ating'leve'r 26 adapted to 'hav'e' a sidewise tal movement hn thexlnn ts of; the

socket. A spring normally presses the lever 26 to its extreme inside position.

dial plate 30 is on the carriage body 3 and provided with a series of perforations 31. 'l he lever 26 is provided with a suitable pin 32 adapted to be engaged in the perforations 31.

In operation, the stop members 12 are adjusted at the proper points in the rack 10 to stop the carriage so that the workpiece A will be successively stopped in the machine for the formation of the holes a, b, 0, (Z, c, f, g, 72, '5, 7', a and Z. However, the holes d, e, f, f, 9, Z and Z are closer to the precedin holes than it is possible to adjust the stops 12, therefore, such holes will be gag-ed by changing the position of the plunger stop 1% by moving the lever around the dial p e 30, thereby rotating the rack pinion d moving the plunger 1 er 1-1 longitudinally relative y to the carriage body For example" it the holes f, f and f are to be termed, as the plunger 1 1 approaches the stop 12, which will stop the carriage in proper position for forming the hole f, lever 26 will be moved around the dial plate a suilioieut number of notches to advance the plunger housing" and plunger a distance equal to the distance the hole f is trom the hole f. The carriage is then advanced until the plunger 14: er ges the stop 12 for the hole 7, the hole I then formed, and after the hole f is termed the lever 26 will be brought back on the dial plate a sufiicient nnmber et notches to retract the plunger 1-1- a distance equal to the distance hole 7 is from the hole f., The carriage is then ad vanced until the plunger 14 again engages the stop 12 for the hole 7, and-the hole will be termed, after the hole f is formed, the lever 26 will be further brought back on the dial plate to its normal or Zero position and the carriage will then be advanced until the plunger 14: engages the stop 12 for the hole 7 and the hole f will be formed,

Any of the groups of holes may be formed in a similar manner to that described for the holes f, 7 and f li hile I have shown. and described only one specific embodiment of my invention, it will be understood that I do not wish to be limited thereto since various modifications may be made without departing from. the scope of my invention defined in the ap pended claims.
